Methods have been developed for the preparation of narrow-bore open tubularcolumns. In this content, condensed gases (butane, chloroethane and Freon114) were used as solvents for the static coating of these columns. Adevice for filling the narrow-bore open tubular columns with solutions incondensed gases has been designed. LÄS MER

The formation of branched tubular organs, such as the mammalian lung kidney and vascular system, is an essential process in animal development. The Drosophila tracheal (respiratory) system provides a genetic model system to study the highly ordered process of branch outgrowth and fusion required to form continuous tubular networks. LÄS MER
